Pressure Washing Guide for Florida Homes & Businesses

What's the difference between pressure washing and soft washing?

This is the distinction that saves your property. Pressure washing uses high-pressure water and suits hard, durable surfaces. Soft washing uses low pressure plus a cleaning solution to kill mildew and algae at the root — and it's what delicate surfaces actually need. Use the wrong one and you etch concrete, splinter wood, or blast water behind your siding.

What surfaces are safe to pressure wash?

• Concrete driveways, sidewalks, and dumpster pads
• Brick and paver patios
• Unpainted block walls
• Heavy-duty commercial entryways and loading areas

Which surfaces need soft washing instead?

• Roof shingles (the black streaks are algae — high pressure tears off granules)
• Vinyl and painted siding
• Stucco and screen enclosures
• Wood decks and fences

What PSI and nozzle should you use for each surface?

Most damage we're called to look at wasn't caused by the machine — it was caused by the wrong pressure or the wrong tip held too close. Use this as a starting point and always test an out-of-the-way patch first:

How does Florida's climate change your pressure washing schedule?

Those black streaks on north-facing walls and roofs are Gloeocapsa magma, an algae that thrives in our humidity — rinsing alone won't stop it returning, which is why a cleaning solution matters. Schedule exterior cleaning before our summer rainy season, work in the cooler morning hours, and always pre-wet and protect nearby landscaping from any solution runoff.

Timing matters more here than almost anywhere else. From roughly June through September, Central Florida's near-daily afternoon storms mean a freshly washed surface can be re-splashed with mud the same day, and the humidity that follows feeds regrowth. The sweet spot is late winter through spring — you get the pollen film off, and surfaces stay clean through the season when you actually use your patio and lanai. Homes on lakes or under heavy oak canopy (a lot of Polk County) regrow algae faster and typically need exterior cleaning every 12–18 months rather than every two or three years.

One more local reality: many Polk County HOAs send violation letters over stained driveways and streaked roofs. A soft wash is dramatically cheaper than the roof replacement some homeowners fear the letter is about — the streaks are algae on the surface, not shingle failure.

How do you pressure wash a driveway yourself?

1. Clear and sweep the surface; move cars and pots, and pre-wet any bordering grass and plants.
2. Apply degreaser to oil spots and let it dwell 5–10 minutes — pressure alone will not lift oil out of concrete.
3. Wash with overlapping passes, keeping the tip 8–12 inches off the surface and moving at a steady walking pace. A surface-cleaner attachment gives an even finish a wand rarely matches.
4. Rinse downhill toward the drainage path, then rinse the landscaping again to dilute any runoff.
5. Let it dry fully before judging the result — damp concrete always looks blotchy.
6. Consider sealing. A penetrating concrete sealer applied to a fully dry, freshly washed driveway slows both staining and algae regrowth — it is the difference between washing every year and washing every two or three.

Budget-wise, a rental machine runs about $60–$120 a day plus detergent, and a driveway is a solid half-day of hot work. That math is why many of our customers fold exterior concrete into a bigger visit — for example alongside a deep clean of the interior, or a post-construction cleanup where the driveway took a beating from trades' trucks and mortar wash-out.

When should you call a professional pressure washing crew?

Anything involving a roof, a ladder, two-story walls, or a chemical soft-wash mix is a job for trained, insured crews — both for the result and for safety. For commercial properties, regular exterior cleaning isn't just curb appeal; slippery algae on walkways is a real liability, and dumpster pads and entryways are the first thing customers (and health inspectors) see. Exterior washing is part of our commercial cleaning and office cleaning programs across Polk County — you can see the kinds of properties we maintain on our commercial work page.
